Research Abstract
An analytical expression for the off-axis magnetic field of an iron-free coil was derived. The electron ray through the field was traced using the iterative method. Special attention was ,therefore,paid to the development of a computer program for calculating the electron trajectory in a system of magnetic lenses with the aid of the general ray equation. The accuracy at each stage may be checked the using energy equation.
